Application filed November 24, 1913.

To-all 'to/10m t may lconcern 1 Be 1t known. that l, EDWARD BOEKENKAMP,

' a citizen of the United States, residing at St. Louis, in the State ofMissouri, have invented certain new. and useful Improvements in Meansfor Raising and Lowering Combustion-Tubes, of which the following is aspecification, reference being had therein to the accompanying drawing.

'My invention relates to improvements in means for raising and loweringcombustion tubes.

vThe object of my invention is to provide means whereby the combustiontubes may be readilyraised and supported away from the wick trough sothat the burner can be readily lighted the burner has been lighted. Thestructure also provides means whereby the combustion tubes may besupported above and away from the wick, so that'the oil by capillaryattraction will not work its way up on the combustion tubes when the'stove is not in operation- In stoves of: this character it has beenfound that when the 'combustion tubes are left in a downward position,resting in a wick trough, the oilby capillary attraction creeps up onthe combustion tubes and causes the stove to smoke when it is firststarted.

Anotherobject of myv invention iis to provide .a simple, cheap andeffective means whereby the combustion tubes can be raised on a burnerin which a wick stop is used and having certain details of structure andcombination of parts, hereinafter more'fully set forth.

Referring now to the drawings: Figure 1 is a vertical sectional view ofa burner showing my improved combustion tube raising device full line inoperative position, and also is arranged inthe usual showing them indotted lines 1n a raised position. Fig. A2 is a detached perspectiveview of the raising lever, showing the same extending through the slotin the guide plate andshowing the combustion tube supporting memberremoved.

'Referring now to the drawings, 1 represents the ordinary wick burnerhaving at its upper end the usual trough 2, in which manner the wick 3;raised 'and lowered by the said wick being but preferably that any idesired means,

shown in dotted lines Fig. 1. ri`he upper end oi the inner wick tube hasa diaphragm i extending across the central opening therein and providedwitha downwardly turned outer edge which is secured to the wick tube bymeans of solder, as .clearly shown in Fig. l of the drawings. Thisdiaphragm 4 is provided with an -upwardly extending portion 5screw-threaded as indicated at 6. This central upwardly extendingportion 5 of the diaphragm is provided with a central opening- 7ltherethrough, the Jurpose of which will be hereinafter more ilullydescribed.

Resting upon the flange 8, ofthe central portion 5 which is formed bythe reduced screw-threaded portion 6, is a wick stop 9. This wick stop,as shown, is of a diskshaped form having perforations. therein andhaving at its outer edge a downwardly vand outwardly extending portion10. The

does not in any way aii'ect the operation of the stop.

Screwed upon the reduced threaded portion 6 of the central portion 5 isa nut 1 which is adapted to screw down upon the wick stop 9 and clampthe saine tightly upon the ledge8 carried by the central portion 5. Bythis structure it will be seen that the wick stop is removable.

The combustion tubes are of the type wellknown having the perforatedouter'wall 13, and inner Wall 14 surrounded by a removable chimney 15,supported by the ring 17 carried by the lower end of the outerperforated tube 13. i This specific structure of combustion tube andchimney and means for supporting it is described in an application filedOctoberQ/th 1913, Serial No. 797,580.

having its upper end reduced and through the said slot is an outwardlyturned end 22 of the rod 23. The outer end of the #outwardly turnedportion 22 of the rod on 'the outside of the plate 19 is provided with a-knob for grasping and operating said rod. This rod is provided with acrank-shaped portion 24, belew the plate 25, carried by the lower end ofthe burner 1, and through which the-rod 23 passes. rThe rod from this4crank portion 24 extends upwardly through the burner and through theopening 7 in the central portion 5, carried by the perfo- *i rated plate4. This rod, as shown in Fig'l of the drawing, extends a considerabledisthe vfertical tance above the threaded portion 6 of thel enlargedportion 5. The upper end of the rod is reduced, as indicated at 26 andadapted to fit in a socket 27 carried by the plate 28. This plate 28, asshown,v is provided with openings for the purpose-of lightening thedevice and also to allow a free passage of ',air up through thelcombustion tubes` This plate 28 rests against the lowenface of thetransverse perforated plate 18 carried by .the interior of thecombustion tube and the through a central opening' socket 27 extendstherein.l

"'When the outwardly turned portion -22- of rodv23 is in the lower end-of the obl-ique,y slot 20, the-combustion tubes 13 and 14 rest' withinthe yflanges on each side of the wick. When it "is desired to raise thewick, all that is necessary to do is to move the outwardlyl turnedportion 22 Aor" the rod 23 to the right, which will-cause it to travelupwardly on the' inclined lower face of the slot and at the same timerotate the rod 23. This causes the rod to travel upwardly and the plate18 of the combustion tube resting upon the plate 28 will cause thecombustion tube to be raised from the anges. The ortion 22 of 'therod'23 is moved to theright until it reaches the straight horizontalportion 21,l whereit will remain with the combustion tubes fraised fromthe flanges so that the burner can be readily lighted. When it isdesired to lower the combustion tube, the portion 22 'fthe rod 23 ismoved to the left, which causes the rod 23 to rotate andat the same timeto travel downwardly to bring the combustion tubes within the flanges,as clearlyr shown yin Fig. 1 of the drawings.

The central upwardly extending portion 5 carried by the diaphragm,- asheretofore ydesc'ribed,.is provided with anopening 7 through which therod 23'passes. This elongated portion 5 serves as a4 guide for the rod23 to prevent any twisting, yet allows of the free movement of the rodtherethrough.

Having thus described my invention,what I claim and desire to secure byLetters Patent is: y

1. .The combination with a burner having combustion tubes, of a wickstop, a diaphragm spanning the space within the inner wick tube adjacentthe upper end and adapted to support the wick stop, a rod extendingupwardly through the burner and through the diaphragm and adapted to suport the combustion tubes and means carried) by the lower end of the rodfor raising and lowering the saine, whereby the combustion tubes areraised and lowered from or to the burner.

2. The combination with a burner having -fombustion tubes, of a wickstop, a plate means carried by the upper end of the rod for supportingthe combustion tubes, and

` means operating with the lower end of the rod for raising and loweringthe same. i 3. vThe combination with a burner having combustion tubes,of a wick stop, a. 'plate spanning the space Within the inner wick tubeadjacent its upper end and rigidly supported thereby, said plate 'havingan upwardlyex-tending sleeve at the center thereof and adapted tosupport' the wick stop, a rod extendiugupwardly through the burner andthrough the said sleeve, a plate carried by the upper end of the rod andsupporting the combustion tubes, and means operating with the lower endof the rod for raisingv and lowering the same, whereby the combustiontubes are raised and lowered on the burner.

4. The combination with a burner having combustionivtubes, of a wickstop, a plate rigidly secured to the inner wicktube adjacent its upperend, a sleeve carried by the said plate and having a screw threadedupper end upon whichis adapted to be secured the wick stop, a nut onsaid screwthreaded portion and a rod extending| upwardly throughtheburner and through the sleeve and adapted to raise and lower thecombustion tubes, substantially as shown and described.
